Hi my friends !!!

First I'm sorry for my bad english i'm from franco-europa lol

I'm very interested by making a sealed rooom and because I'm very bad in english I' can't find easly good infos....

I have understand (I hope) the mains infos..but I wonder how the plants are enough oxygen for the night...

She needs only the oxygen present on the area when lights come off when CO2 is at 1300/1500PPM...ou she needs a supplement like a bottle of oxygen with a solenoid?

Thank you in advance for your advice

All the best

if its sealed i assume you have an ac ? dehumidifier? the only reason i vent at lights off is to keep humidity in check. no bottled oxygen needed and possibly dangerous. no co2 at night

i have a sealed room but i keep the level at 1000ppm.
you dont need to supplement oxygen because the plants produce o2 during the light cycle.

I have an A/C 12000btu for 6K lights with Supersun2 glass sealed and all hot extract are connect to ice box from hydro-innovation...my box is realy completely sealed

my A/C is a whirlpool 92/1 with 6th sens fonction which automatically adjusts the temperature (22/24 it is in heating mode, between 24 and 28 it is dehumidified and after he becomes A / C )

yes there i a thread on that subject it seems results have shown that 1000ppm is the optimum level higher levels are a waste of co2

[k1k1]

ha agreed ... this is what has been scientifically tested or tests on ICmag?
